ABSTRACT

A fender for a lawn mower having tire wheel assemblies that are mounted to a yoke of a swivel caster assembly, whereby the yoke pivots through 360 degrees of rotation, includes an arcuate fender body. The fender body is attached is attached to the yoke by a bracket so that it is rotatably carried by the rotating yoke. As such, the fender body is maintained at an optimal position relative to the mower tire, and thereby provides desirable deflection of lawn clippings and other debris from the various operational components provided upon the mower deck. This prevents the premature wear of such operational components, thereby decreasing down time and reducing maintenance costs of the mower.

TECHNICAL FIELD

Generally, the various embodiments disclosed herein relate to lawnmowers. In particular, the various embodiments disclosed herein relateto fenders for lawn mowers. More particularly, the various embodimentsdisclosed herein relate to fenders for lawn mowers having one or morewheels mounted on a swivel caster, such as in the case of a zero-turnlawn mower.

BACKGROUND

Zero-turn lawn mowers, also referred to as zero-turn-radius lawn movers,include a body in which their front wheels are mounted on rotatableswivel caster assemblies. This allows the zero-turn lawn mower to haveexceptional maneuverability. However, when the mower is operated, anddue to the nature of these rotatably mounted wheels, lawn clippings andother debris are readily directed onto a mower deck mounted behind thefront wheels. Such debris is permitted to become incorporated into themechanical mechanism, which includes various pulleys and belts, thatdrives the cutting blades. This causes the premature deterioration orwearing out of the blade drive mechanism, resulting in increasedmaintenance, increased cost, and increased down time of the mower, allof which are unwanted.

DETAILED DESCRIPTION

Various embodiments of a fender assembly 10 for use with a mower 20having one or more wheels that are mounted on swivel caster assemblies30, as shown in FIG. 1.

The mower 20 includes a zero-turn lawn mower, and a zero-turn radiuslawn mower, as well as any mower having tire wheel assemblies forcarrying the body of the mower over a surface, such as a lawn, that aremounted to the swivel caster assembly 30 to be discussed in detailbelow. The swivel caster assemblies 30, shown clearly in FIGS. 2-5,includes a yoke 100, from which extends a swivel shaft 110. The swivelshaft 110 is configured to be rotatably received within a swivel housing120 that is attached to the chassis 132 of the mower 20.

The yoke 100 includes two spaced apart yoke arms 150A and 150B that forma gap 151 therebetween. The yoke arms 150A-B are joined at substantiallyright angles by a cross-member 152, and the yoke arms 150A-B each havean aperture 160 disposed therethrough. The apertures 160 of the yokearms 150A-B are provided to receive, or to be attached to, an axle 170that rotatably carries a wheel assembly 180 thereon. The wheel assembly180 includes a hub 182 and a tire 184 mounted thereon. In someembodiments, the axle 170 may comprise a threaded bolt 186 that isretained to the yoke 100 by a nut and washer assembly 188.

The swivel shaft 110 extends from the cross-member 152 of the yoke 100at a substantially right angle, and is cylindrical in shape and freelypivots or rotates 360 degrees within the swivel housing 120. As a resultof this rotation, the swivel caster assembly 30 allows the yoke 100 andthe wheel assembly 180 carried thereby to rotate or pivot freelytogether through 360 degrees. The swivel housing 120 includes agenerally cylindrical cavity 190 to accommodate the cylindrical shape ofthe swivel shaft 110 received therein. In some embodiments, the swivelshaft 110 may be rotatably carried within the swivel housing 120 bysuitable bearings and/or bushings. In addition, in some embodiments, theswivel shaft 110 may be retained within the swivel housing 120 by anysuitable fastener or device, such as retaining pins, retaining clips, orretaining clamps and the like. In one embodiment, as shown in FIG. 3,the swivel shaft 100 may be retained within the swivel housing 120 usinga screw 200 that is received through a retaining washer 202, which isthreadably received within an aperture 206 disposed in an end of theswivel shaft 110 that is distal to the wheel assembly 180.

It should be appreciated that in some embodiments, a bottom edge 300 ofthe swivel housing 120 is spaced away from a top surface 310 of thecross-member 152 of the yoke 100 to form a gap 330.

The components of the swivel caster assembly 30 may be formed of anysuitable material including metal, polymeric material, or compositematerial.

The fender assembly 10 includes a fender body 400 that is curved orarcuate in shape. In some embodiments the dimension of the radius ofcurvature is configured to match or follow that of the tire 180, but isnot required, as other dimensions may be used. Continuing, the fenderbody 400 is formed of a continuous or elongated body section 402 havingan inner surface 404 and an outer surface 406. The fender body 400 isbounded by lateral edges 410 and 420 that are joined at top and bottomedges 430 and 440, respectively. Disposed in the top edge 430 is anarcuate, curved or concave cut-out 450, but may be omitted in someembodiments of the fender body 400. The body section 402 may have anysuitable thickness, and may be formed form any suitable material, suchas metal material, polymeric material, including plastic, as well ascomposite materials, and the like. While the edges of the fender body400 are discussed herein as forming a substantially rectangular shapethat is bent about a desired radius of curvature, the edges of thefender body 400 may be rectilinear, curvilinear, or any combinationthereof. Furthermore, the top and bottom edges 430 and 440 may havedifferent dimensions, and the lateral edges 410 and 420 may be differentdimensions.

The fender body 400 is mounted to the yoke 100 by a bracket 500. Thebracket includes spaced arms 510A and 510B that are joined by across-member 502. Disposed through each of the arms 510A-B are mountingapertures 520, and disposed through the cross-member 502 is one or morefender mounting apertures 530. The mounting apertures 520 are configuredto receive or be attached to the axle 170, so as to retain each of thearms 510A and 510B adjacent to respective yoke arms 150A and 150B. Inaddition, the fender apertures 530 are provided to allow the bracket 500to be attached to the fender body apertures 560 disposed through thefender body 400 using any suitable fastener, such as screw and washerassemblies 570 for retention by washer and nut assemblies 571. It shouldbe appreciated that the bracket 500 may be configured to use only one ofthe arms 510A or 510B. In addition, the bracket 500 may be formed insome embodiments without the use of the cross-member 152. In someembodiments, the bracket 500 is attached to the fender body 400 at ornear the apex of the curvature of the fender body 400. However, thebracket 500 may be attached to the fender body 400 at any position onthe fender body 400. In addition, in some embodiments, the bracket 500may be positioned so that the arms 510A-B are at about a 45 degree anglerelative to a vertical axis extending through the swivel housing 120.However, the arms 510A-B may be positioned at any desired angle relativeto such vertical axis. The bracket 500 may be formed of any suitablematerial, such as metallic material, polymeric material, or compositematerial. In some embodiments, the bracket 500 may be made integral withthe fender body 400 to form a single piece. In further embodiments, thebracket, fender body 400 and yoke 100 may be formed as an integralpiece.

Thus, when the fender body 400 is attached to the yoke 100 by thebracket 500, the curvature of the fender body 400 allows the fender body400 to clear and avoid contact with the chassis 132 of the mower 20 asthe yoke 100 is rotated through its 360 degrees of rotation. That is,during operation of the mover 20, the fender body 400 is freely carriedby the rotating yoke 110 through the 360 degrees of rotation in anuninhibited manner. Thus, the fender body 400 is able to deflect debrisand lawn clippings during the forward movement of the mower 20, whilebeing rotatably carried by the pivoting or swiveling yoke 100. Such aconfiguration of the fender body 400 avoids the difficulties that wouldoccur if such fenders were not rotatably carried by the swiveling yoke100, but statically affixed to the chassis 132 of the mower, especiallyin retro-fit situations where the chassis 132 design may vary greatlyfrom one lawn mower to the next. Further, by configuring the fender body400 for attachment to the swiveling yoke 100, the fender 400 is madecompact and enabled to accommodate a large number of mowers 20, therebyavoiding operational interference with the various chassis structuresutilized across different mower 20 designs.

It should be appreciated that in some embodiments, the bracket arms510A-B may be positioned to the inside of the yoke arms 150A-B so as tobe within the gap 151, or may be positioned to the outside of the yokearms 150A-B.

In other embodiments, the bracket 500 may be attached to any portion ofthe yoke 100, including the yoke arms 150A-B, and the cross-member 152.The bracket 500 may be attached to the yoke 100 using any suitablemeans, including removable or non-removable attachment means, such asnuts/bolts, welding, adhesive, rivets, and the like. For example, insome embodiments, the mounting apertures 520 of the bracket 500 may beused to mount the bracket to any portion of the yoke arms 150A-B.

In some embodiments, the concave or arcuate cut-out 450 of the fenderbody 400 may be positioned within the gap 330 that is formed between abottom edge 300 of the swivel housing 120 and the top surface 310 of thecross-member 152 of the yoke 100, as shown in FIG. 4. Thus, in somecases, the cut-out 450 is captured or retained within the gap 330, sothat the swivel housing 120 applies a downward force to the top edge 430of the fender body 400. However, in other embodiments, the cut-out 450,due to the curvature of the fender body 400, is not captured or retainedwithin the gap 330, but merely rests within the gap 330 without theswivel housing 120 applying any downward force to the top edge 430 ofthe fender body 400. In still other embodiments, as shown in FIG. 5, thefender body 400 may be configured so that the cut-out 450 is spaced awayfrom the swivel housing 120 by a gap 600.

It is also contemplated that the fender body 400 may have any suitabledimension to accommodate wheels 182 and tires 184 of various sizes,including radius of curvatures, width, and profiles for example.

In still other embodiments, the top edge 430 of the fender body 400 maybe configured to extend over top of or underneath at least a portion ofthe yoke cross-member 152. However, in some embodiments, the fender body400 may extend so that it does not extend over the top of or underneaththe yoke cross-member 152. In other embodiments, the top edge 430 of thefender body 400 may be spaced apart from the yoke 100 by a gap.

In other embodiments, the fender body 400 and the bracket 500 may beprovided as unassembled components in a kit for retrofit attachment tothe mower 20, or alternatively may be attached to the mower at the timeof the original manufacture of the mower 20.

Additionally, the fender body 400 may extend along its longitudinal axisany desired length to provide the desired coverage of the tire 184.
